Great, thanks.
One more question. Doing it the mris_glm way, is there somehow I can turn the beta files (bfloat) into ascii surface format? Thanks,

The easiest way is probably to build an average subject (make_average_subject). This will create ?h.thickness in the surf dir which will be the average across the input subjects. You could also use mris_glm with a design matrix of all 1s. The beta output will then be the average thickness.

Hi, I feel like I used to know this, but how do I make a map of average thickness for a group of subjects? Also, is there a way I can make a similar map showing the variance of thickness values? Thanks,
